Well, you’re assuming a display module only contains a display. See my original comment: > with a knock off display/touch module I don’t agree with this, > they would not have a business > Conformance is easy to validate due to the very limited scope This is difficult to respond to, since we come from such different backgrounds. Your assumption is that there is reasonable QA, for a knock off part. Even though this is a logical assumption to have, it is incorrect. QA can very often be, does it work in this device we have right here? And, implementing a hardware interface correctly doesn’t mean much when you, for example, attach a flex that makes the signal marginal.
